If the spray'projectur isfor use above the basket of dishes in the'wa'shing machine thenthe perforations--23are located along the bottom sides of the spray jtubes; -I'I'he' particular spray projector is intended also for location below the dish rcontaining basket of the Washing machine in the inverted position."

A means is provided for automatically cutting" off the passage of the liquid through the openings 23 so as'to prevent dripping when the liquid supply is cut ofi. This means comprises sleeves 24-slidably engaged upon the tubes 22. andformed with closed ends 25 so as to cause an urge which will tend to move the tubes outwards when there is liquid pressure within the spray,y projector. The

`sleeves 24 are longitudinally slidab'le` upon the tubes within limits as determined. by pins 26 proL jecting from the tubesV 22 fand engaging in small longitudinal slots 2'! formed in the. sleeves V24. The sleeves 24 are provided with perforations 28 adapted in one position ofthe sleeves toIv align with theperforations 23 in the spraytubes and infanother'position to be out'of alignment. More I particularly it is necessary that the perforations 28 be'out oi alignment with the`perforation's V23 when the sleevesr24 are in the` retractedpositions. A resilient means is vprovided' for' norally urging the sleeves 24 into the' retractedjpositions and comprises springs 2S' arranged coaxially uponthe spray tubes 22, and the sleeves 24 immediately atthebasesof the spray tubes. These springs have one of vtheir endsV 38 attached upon the' spray tubes 22 and other of their. ends 3D attached upon the sleeves 24 and so provide the necessary urge to move theyV sleeves 2'4 into the'retracted positions. .These springs 2.9 arefof such strength as to give undery thepressureof the owing liquid within theY spray projector 'so that the sleeves 24 maymoveV automatically'to the`A` extended positionsras allowedrby the slots 2,1. In thesey extended positions the perforations 28. arein line with the'perforations 23 andlsoV allow the passageof the liquid through the perforations.

The hollow member i3 is also "provided with a plurality of liquid passagepeningsj3l arr- Y ranged at thebottom of thefhollow` member and adapted toA direct thejliquid ldownwards at the center of the spray projector. VAn'arrangement is'also provided for preventing drippingv through `these perforations. This arrangement comprisesal pair orslides 32A slidably mounted uponr the bottom ofthe hollow member i3 and formed with perforations 33 adapted to alignwith theperforations 3l in spread positions of theslides 32.

The slidable mountingV of the slidesis accomplished by vheaded* 'studs .34 mounted upon the bottom of the hollow member I3 and projected throughv longitudinal slots SfformedV upon the slides 32. VSeveral arms 35 connect one of the slides 32f with the sleeve 24 nearest it and other similary arms 36 connect the other slide 32 with the other sleeve 24. Thenofrmal positions'of the slides 32 is illustrated in Fig. 3 ofthe drawing in which the perforations 3|y are cut oil.V Simultaneously with the motion of the sleeves 24 to their extended positions the slides will be correspondingly moved and the periorations 33 aligned with the perforations 3l simultaneous `with the alignment of the perforations 28 withA the perforations 23.

A flexible fin 31 of rubberrrurietalporl any other suitable substance is shown mounted upon each of `the outer ends of the sleeves 24. These ns are intendedto coact with a trip stop arranged upon the dish Washing and drying machine so as to stop rotation ofthe spray projector when the liquid supply is cutoff. n It will readily be understood thatdue tofmomentum the spray projector will tend to rotate and this motion will cause `the tendency of dripping to be amplified. Consequently, it' is paramount that rotation of the spray projector be arrested at the earliest moment, after the liquid supply is cut ofi. The details of the automaticl tripping is illustrated and' described inthe; application mentioned :lat-
